Just as an experiment to see if it makes any difference, try
LW 4.1.4 beta . Doing so has solved a number of other people's problems. Sometimes a specific version of LW doesn't run well on a specific computer configuration, yet the previous or next version runs perfectly. If you want to find out more about LW 4.1.4 before dwnlding it, see:
